As regard the bank statement

[Mahmoudmoussa]

Dear sir,

I'm applying for tier 5 visa sponsored by the royal college of obstetricians and gynecologists through a hospital, I have read that the bank statement should be at least of 90 days duration. The problem is that i have a bank statemant of more than 3000 GBP, but unfortunately, for 2 months only. Can I apply for it now or should I wait for 90 days as said, my sponsor is type A as regard tier 2 but not tier 5.
Thank you
